低能耗节点位置未知无线传感器网络控制方案

介绍了一种低能耗节点位置未知的网络控制方案,根据不同的网络运行轮数设定网络节点的通信半径,使网络具有良好的能量有效性.网络中基站经过构建阶段的启动过程、节点信息收集过程和节点信息上报过程,获得了整个网络节点的相对位置分布,然后整合节点-节点信息支路,得到具有回路链接的簇首节点集,其他节点根据自己邻居信息选择簇首节点,实现网络近似最小能耗拓扑的构建.通过仿真与同类典型算法LEACH-C、MCLB进行比较,结果显示该方案应用于网络运行时具有更长的网络生命周期、更少的信息总数和更低的网络构建代价.

Control scheme for low-energy-consumption and unknown-node-position WSNs

The paper introduces a low-energy-consumption and node-position-unknown network control scheme in wireless sensor networks.The node communication radius is set by the network operation number of rounds for good energy efficiency.The base station obtains the relative position distribution of all sensor nodes in the network after the network construction stage which contains three processes,including initiating process,node information collection process and node information report process.Then,the base station merges the information branches and gets some cluster head node sets each of which forms a loop link to enable good data transmission reliability.Other nodes choose their cluster heads according to the information of their neighbor nodes and an approximate minimum energy topology construction is completed.The proposed network control scheme is compared with the typical algorithms LEACH-C and MCLB.The simulation results show that the scheme used in the network has a longer network lifetime,less amount of data commutation and lower network construction cost.
